Shay Banon (@kimchy) about ElasticSeach integration with CouchDB:
The CouchDB River allows to automatically index couchdb and make it searchable using the excellent
_changes stream couchdb provides. […] On top of that, in case of a failover, the couchdb river will automatically be started on another elasticsearch node, and continue indexing from the last indexed seq.
Full text indexing in the NoSQL space seems to see some interesting solutions.

_changes, you should check the video below:
